2-4 Preparing the Mass Spectrometer for Operation
Verifying the instrument’s state of readiness
When the mass spectrometer is in good operating condition, the power and
Operate LEDs show constant green. You can view any error messages in
IntelliStart software.
Monitoring the mass spectrometer LEDs
Light-emitting diodes on the mass spectrometer indicate its operational
status.
Power LED
The power LED, to the top, left-hand side of the mass spectrometer’s front
panel, indicates when the mass spectrometer is powered-on or powered-off.
Operate LED
The Operate LED, on the right-hand side of the power LED, indicates the
operating condition.
See the mass spectrometer’s online Help topic “Monitoring the mass
spectrometer LEDs” for details on the Operate LED indications.
Tuning and calibration information
You must tune and calibrate the mass spectrometer prior to use. You can
perform these tasks using IntelliStart software.
For further instruction, see the mass spectrometer’s online Help topic
